Tetra Morning Stress

[Uriel]

My Red phantom Tetra seem to be stressed in the morning when i turn the tank lights on. I'm not sure if it's something that is happening in the tank overnight (ph swing maybe ?) or the shock of the lights coming on. But they seem to keep the fins close to there body if that makes sense and lose a lot of there color. As the day progresses they seem better and by evening they have there fins fully out and are properly coloured.

Two of them have also developed a little bit of fin rot. I have just been treating this by upping water changes.

Cheers they normally colour up shortly after the lights are put on just that first thing they are pale. I'm probably just being paranoid, because everything is going so well. I'm expecting my tank to catch fire or something

I hate the morning too.
